[2] Under plans approved in early 2011 for the redevelopment of the RAF station, the house will be renovated and converted to include a restaurant.

The first house on the site was built as a hunting lodge in 1717 for the Duke of Schomberg, a British army commander of German origin.

[5] The Marchioness lived there until her own death in 1804, upon which the estate passed to her stepsister Elizabeth, widow of William Weddell MP.

Her husband had left her Newby Hall in Mayfair, therefore having no need of Hillingdon House, she sold it to Josias Du Pré Porcher in 1805.

"[5] The house and gardens, together with the surrounding parkland and artificial lake created by damming a section of the River Pinn, amounted to more 200 acres (81 ha).

[4] Local opposition to the plan led to the house becoming the Canadian Convalescent Hospital to care for troops evacuated from the front line during the First World War.

Needing a site for the training of recruits in ground gunnery, the RFC used parts of the estate not required by the Canadian hospital and established a firing range on the opposite side of the river from the house.

11 Group formed on the same day under the command of Air Vice Marshal Philip Joubert de la Ferté, using Hillingdon House as its headquarters.

[14] Southern Region Air Traffic Services HQ and the Royal Observer Corps' South East Communications Centre moved into the house in 1960.

[18] On 31 March 2010, RAF Uxbridge closed as part of a rationalisation of Ministry of Defence facilities in Greater London.
